Make sure that your shoulders are firmly held against the floor, and keep your elbows tucked to the sides. The Kettle bell single-arm floor press is a unilateral chest exercise, meaning you work one side at a time.
They aid you in growing a full, thick chest; they add great variation to chest day, and it is a shoulder friendly exercise for those who may have had a past injury. This is because you have the full support of the floor which limits your range of motion on the descending portion of the exercise.
It takes superior limb control to lift unilaterally. You may wake up some sleeping stabilizer muscles that you might not necessarily be utilizing with bilateral lifting methods (two-handed).
Lie flat on the floor with your feet extended outward. Press the kettle bell straight up toward the ceiling, rotating your wrist so that your palm is facing forward.
Lower the kettle bell back to the starting position and repeat for the set. Avoid injury and keep your form in check with in-depth instructional videos.
“So, do Get Up's, and get the bell in position with a floor press, you are doing it, and not too much volume to put stress on your shoulders. I'm sure Brett knows what he's doing, but for other people, make sure the center of the weight is straight above your elbow.
Personally I'd say you will get many times more utility from PU variations up to and including Oahu. The ROM on the floor press is very constrained compared to other prone pressing. Not saying it is a poor exercise overall, but IMHO it can be substituted for better lifts and by itself is more of a rehab or short term lift to help with sticking points in the full press.
Floor press (kettle bell, dumbbell, barbell) absolutely is worth doing if it aligns with your goals. I recently got very strong results just using my KB's like dumbbells and doing chest press using a sandbag for a bench.
Are there any benefits the one arm press doesn’t give that the floor press does? It is easy to learn and requires less equipment than bench press.
But since I own a small gym with only one rack I mostly teach FP to my students. I had a lot of students with shoulder problems and rarely it happened that there was nothing I could do.
It is very easy to learn how important the tension is when doing single kettle bell FP. It is almost impossible to press the kettle bell (even light ones) without activating your abs/glutes/lats/hamstrings/you name it... Great way to teach tension and shoulder packing for a press in general...and you don't even have to know how to clean a kettlebell.
